' Application filed April 19. 1917. Serial to. 1e3,319.'

To all whom it may concern:

Be it known that we, JAMEs CLARKE HA- GEY and ALFRED SWENSEN; citizensof the United States, residing at Chicago, in the county of Cook andState of Illinois, and Cicero, in the county of Cook and State ofIllinois, respectively, have invented certain new and usefulImprovements in an Inclicatlng'Device Usable with Music-Record- 1I10'Mechanlsms, of which the following is a full, clear, concise, and exactdescription,

reference being had to the. accompanying drawings, forming apart of.this specifieae tion. y

Our invention relates to an indicating device usable withmusic-recording mechanisms, and more specifically, to an indicatingdevice for use with recording machines which make recordsof selectionsas they are played on musical instruments.

One of the objects of ourinvention is to provide an indicatingdevicewhich will indicate to the attendant orv to the-performer playing aselection, the speed atwhich the record-receiving means on which therecord is being made, is being advanced. A further object of ourinvention is to provide'an indicating device which will act periodically011 the person of the attendant or performer to enable him to. make thetempo, at which a selection is being-played conform to the speed atwhich the record-receiving means is being advanced. A further object ofour invention is to provide an indicating device in which the periodicactuationsreferred to will be recorded on the record'- receivin'g'meansitself. Further objects will appear from the detailed descriptionto-follow and from the appended claims. I

In the drawings, in which one embodiment of our invention is shownp IFigure 1 is a sectionalside' elevation, showing a grand piano,a'recording device mounted thereon, and an indicating device inconnection therewith; i

Fig. 2 is a plan view of aperiodically acting, pneumatic indicator, towhich the foot of the attendant. or performermay be secured, part beingshown in section, on the line 2-2 of Fig.3; I

Fig. 3 is a s1de elevation of the parts make Fig. 8 is a section, on theline 8-8 of,

Fig. 9 is a side elevation, showing interchangeable spur-wheels used forcontrolling theindicatorp Referring to the drawings in detail, ourinvention is shown in connection with a grand piano 10, arecordingmechanism 11 for recording, on a record-recelvlng means 12; the playingof a selection as it is played on the piano 10; periodically acting,pneumatically actuated, indicating means 13,

acting on thefoot i l of the attendant or performer for indicating thespeed at which the record-receiving means 12 is being advvancedycontrolling means '15, controlled .bythe record-receiving means12, for con trolling the periodically acting, indicating means 13;andrecording means 16 for recording, on'the record-receiving means 12,the periodic actuations of the, indicating means 13.

In the exemplification of our invention shown the record-receiving means12, on

which the record; of the selection played is made, may be a sheet whichis afterward perforatechin accordance with the record fmade, and used asa master-sheet in an automatic perforating machine to control the Thisrecord-receiving means 12, which is used to a master-sheet, is providedwith a series of alined openings 17 (Fig. 7) adjacent one edge thereof,into which may enter' the teeth 18 of a spurfeed-wheel 19, which is sorotated as to cause the record-receiving means 12 to advance at thedesired speed.

The record-receiving means 12 may be held in-proper relation to the spurfeed-wheel 19 Patented Oct. 4, 1921 shown in Fig. 2, part being shown insecsection, on the line l vproductionof perforated music-rolls for use pvwith 'automatlc musical lnstruments.

by means of a roller 20, which has a groove 21 to afford clearance forthe teeth 18 of the feed-wheel. The recordreceiving means may be drawnover a suitable platen 22 beneath the recording devices 11 and 16.

The recording mechanism 11 may be of any suitable type and, as shown,comprises a series of markers 23, (one for each key 24 of the piano)slidably mounted in a supporting frame 25; a spring 26 for each marker23, for normally holding the marker out of contact with therecord-receiving means 12; a bell-crank-lever 27 for each 'matio 31, thevalve-action 32 is made to comprise four diaphragm-actuated valves 34,the diaphragm-chambers 35 of which are all connected with a conduit 36through a trunk-passage 37 and branch passages 38 (Fig. 6). Each of thevalves 34 controls a passage 39 leading to the interior of the pneumatic31 (Figs. 3 and 5). Each valve 34, in its raised position, places thepneumatic 31 in communication with the suction wind-chest 40 through itsrespective port 41, and, in its lowered position, places the pneumaticin communication with the atmosphere through its respective port 42. Ahousing 43 may be provided to prevent foreign substances from gettinginto the valve actions. The suction wind-chest 40 may be placed incommunication with any suitable source of rarefied air 44 (Fig. 1)through the passage 45 and conduit 46. Any suitable restricted vents maybe provided between the diaphragm-chambers 35 and the wind-chest 40 toinsure the proper operation of the diaphragms 47.

The controlling means 15, for controlling the periodic actuations of thepneumatic 31, comprises a valve-device 48 (Figs. 1, 7 and 8) forcontrolling the admission of air through the conduit .36 to thediaphragm chambers 35; a spur-wheel 49, provided with a number of pins50 for operating the valvedevice 48; and with projections 51 spaced soas to enter the openings 17 in the recordreceivin means 12' and a swinin arm 52 pivotally mounted at 53 on the frame 25, said arm having abearing 53 on which the spur-wheel 49 is rotatably mounted, and to whicharm the valve-device 48 is secured (Fig. 8). The valve-device 48comprises a port-block 54, the port 55 of which is in communication withthe conduit 36; a leafspring-valve 56, controlling the port 55 andhaving a portion extending into the path of movement of the pins 50; anda pair of brackets 57, secured to the port-block 54 by means of screws58 and to the swinging arm 52 by means of set-screws 59. The pivotalmounting of the arm 52 permits it to be moved toward or from therecord-receiving means 12, so that different sizes of spurwheels 49(Fig. 9) may be interchangeably mounted on the bearing 53. The pins 50may be slidably mounted in the spur wheel 49 (Fig. 9) (Fig. 7) so that,if desired, certain of them may be moved to a position in which theywill not engage the leaf-spring valve 56 in their movement. Thus, thespeed of the indicating means 13, with respect to the speed of therecord-receiving means 12, may be varied either by an interchange ofspur-wheels 49 orby a withdrawal of some of the sliding pins 50.

The recording means 16, which makes a record on the record-receivingmeans 12 of the periodic actuations of the indicating means 13,comprises a marker 60 slidably mounted in the frame 25, a spring 61 fornormally holding the marker 60 out of contact with the record-receivingmeans 12, and a pneumatic 62 controlled by the spurwheel 49 fordepressing the marker 60. The pneumatic 62 is controlled from thespurwheel 49 in a manner similar to that in which the indicating means13 is controlled.

To accomplish this, the valve-action 63 of the pneumatic 62 is connectedthrough the conduit 64 with a port-block 65, which is mounted on theport-block 54, both portblocks being thus carried by the swinging arm52. The port 66 (Fig. 8) of the portblock 65 is controlled by means of aleaf spring-valve 67, which has a lost-motionconnection 68 with theleaf-spring-valve 56. The lost-motion-connection 68 comprises a rod 69which extends through openings in both of the leaf-spring-valves 56 and67, two buttons 70 threaded on the rod 69 on opposite sides of theleaf-spring-valve 67 and a head 71 on the rod 69 beneath theleafspring-valve 56. The rod 69 extends loosely through the opening inthe lower leafspring-valve 56, and the head 71 is spaced from the valve56 when both the valves 56 and 67 are closed. By this construction,openin of the valve 56 will also cause the valve 6 to open, but thevalve 67 will open later than the valve 56. By adjusting the buttons 70,the retardation of the valve 67, with respect to the valve 56, may beadjusted The lost-motion coupling of valves 56 and 67 preventsinterference by either valve with the proper action and closure of theother, and the adjustable feature of the coupling permits proper timingof the relative operation of the two valves, which may be desirable ininstances where the recording mechanism 11 is located at a point distantfrom the piano 10 and the indicating means 13, or from either of them.

The wing-chest of the valve-action 63 may be connected with the sourceof rarefied air 44 through a conduit 73.

The means 33, for securmg the foot of the attendant or performer to thepneumatic 31 and positioning it with respect thereto, comprises aheel-plate 74, secured to the movable leaf 75 of the pneumatic 31 andhaving an upstanding flange 75 for engaging the heel of the shoe; and anadjustable toe-clamp 76, for holding the forward part of the foot inproper position. This toe-clamp 76 comprises a slide 77, slidable on themovable leaf 75 and provided with slots 78, through which the guidingand securing screws 79 extend; and a metalbracket 80, extending out overthe forward part of the foot of the attendant or performer and providedwith an adjustable cushioned clamp 81, which clamp is supported by thebracket 80 and is'adjustable with respectthereto and with respect to theforward part of the footof the attendant or performer by means of athumb-screw 82.

For'limiting the collapsing movement of the pneumatic 31, the screw 83is provided. This screw is threaded through a bracket 84 secured to themovable leaf 75, and, when the pneumatic collapses, engages a stop 85secured to the fixed leaf of the pneumatic. A lock-nut 86 maybe providedforholding the screw 83 in adjusted position. In addition to limitingthe collapsing movement of the pneumatic 3 1,the screw 83 and stop 85also serve to give an audible signal when the screw'strikes the stop.The use and operation of the device will now be described. When it'hasbeen decided to record a certain musical selection, the person in chargeof the apparatus,upon examining the score of the selection or afterlistening. to a preliminary renditionthereof, determines at what speedthe record-receiving means 12 '(which is to be made into a master-sheet)is to be advanced, and also decides what the frequency of operation ofthe indicating means 13 should be. The

various considerations which determine the speed at which therecord-receivingmeans should be advanced and the frequency with whichthe indicating means 13 should be actuated do not need to be gone intoin detail. The person in charge, from; this knowledge of therequirements, determines the distance which the record-receiving means12 should travel. for each measure of the selection, and determines thenumber of times which the pneumatic 31 should be actuated for each suchmeasure. He then arranges so that the feed-wheel 19 will drive therecord-receiving means 12 at the required speed, and chooses aspur-wheel 49 which will cause the required number of actuations of thepneumatic 31 for a given advance of the record-receiving means 1.2. Thefoot of the attendant or performer is secured toithe 46 and. 78. Theadvancing of the recordreceiving means '12 causes the spur-wheel 49 torotate, and the pins 50 are thus moved to engage with the.leaf-spring-valve 56 to periodicallyopen this valve. The opening of thevalve 56 causes the pneumatic 31 to collapse, to impart a downwardmovement to the foot of the attendant or performer. As the pins 50disengage from the leafspring-valve, the valve-snaps shut, permittingthe pneumatic 31 to expand under the action of the spring 87. Theopening of the valve 56 also opens the valve 67 through thelostTmotion-connection 68, causing the pneumatic 62 to collapse(simultaneously, if desired) with the collapse of the pneumatic 31. Thecollapse of the pneumatic 62 moves the marker 60 down into engagementwith the record-receiving means 12 to make a mark thereon. When thevalve 56 snaps closed,

the valve 67 also closes, permitting the pneumatic 62 to expand, andthespring 61 to 11ft the marker 60 away from the recordrecelvmg means12.

The attendant or performer plays the selection, and the recordingmechanism 11 makes a record on the recordreceiving means 12 of theselection as it is played, the depression of the keys 24 causing thedepression of the corresponding markers 23 through the flexibleconnectors 28 and the bell-cranlr-levers 27.

The attendant or performer, knowing the number of collapses of thepneumatic 31 which will take place for a given travel of the.record-receiving means, is enabled to play the selection so that eachmeasure thereof will be recorded onthat portion of the record-receivingmeans 12 on which it is desired that it should be recorded.

The marks made on the record-receiving means 12 by the marker 60, whichrecords the actuations of the pneumatic 31, enable the arranger, who hascharge of the perforating of the record-receiving means 12, to detectinaccuracies in the record caused by an imperfect rendition ofthe'selection as to tempo, as these marks made by the marker 60 indicatethe .bars, which divide the meas ,ur'es from each other, and thesubdivisions of the measures of the selection.

The instrument used is not necessarily an which are operated manually bythe fingers of a performer, as it is sometimes desirable to use ourinvention in connection with automatic musical instruments provided withmeans, manually controllable by an attendant, for controlling the tempoin accordance with the actuation of the indicating means 18. Thissuggested arrangement may be used for various purposes. It may be usedto change the rhythm-that is, to produce a new music-roll'in which therhythm is different from the rhythm of the music-roll used on theautomatic instrument-or it may be used to change the length of themusic-roll-that is,'to produce a new roll which will have a differentlength from the roll used in making the record. It may also be used formaking additions to the roll.

In the claims, where the expression manually attended musical instrumentis used, it is to be understood as including an automatic musicalinstrument, provided with means manually controllable by an attendant,as well as a manually playable musical instrument, Such, for instance,as we have shown.
